Anglo American Australia workers herald new frontline safety program

Anglo American has leveraged the experience of its coal mine workers to devise its new frontline safety program, the Fatal Risk Management (FRM) program.

Through a bottom-up approach, frontline workers have been empowered to shape FRM, a program that, the company says, is easy to use and doesn’t add another layer of red tape.

Anglo American Australia CEO, Dan van der Westhuizen, said embedding frontline workers in the project team was crucial in designing the simplified and standardised tools as they understood the risks better than anyone else. He said the team included a mix of operators, coordinators, supervisors, superintendents and contractors across its Bowen Basin operations.

“Fatal Risk is not a new concept for the mining industry and learnings from our people, peers and industry experts have informed our approach,” he said. “Our point of difference has been cultivating FRM from the operator level to leverage the insights and experiences of our frontline workers to ensure we have the best chance of getting it right.”

The FRM program comprises 14 Fatal Risks and 50 crucial Fatal Controls that sit underneath risks and these must be in place to help prevent a fatality from occurring at the frontline. Every job. Every time.

“These 14 Fatal Risks are sobering because they represent circumstances where a teammate in our business or industry has lost their life or been seriously injured on the job,” van der Westhuizen said. “It’s not often you get a chance to stop, take a step back and create a new way of working but we knew we had to make a change. Everyone deserves to go home to their families, friends and loved ones at the end of every shift.

“We know change is not easy and a culture doesn’t change overnight, but we know we are moving in the right direction.”

Anglo American was a finalist in the 2024 Prospect Awards for the rollout of its FRM project – created by the frontline, for the frontline.

Capcoal Exploration Supervisor, Will Parfitt, who has been in the mining industry for more than 17 years, said he had been proud to represent his colleagues as a member of the Fatal Risk frontline team.

“There is nothing more important than the safety of my colleagues across Anglo American and this is one of the most important things I’ve done,” he said. “I’m really proud to be involved. We now have one universal Take 5 book and Job Risk Assessment template across all operating divisions – among the last lines of defence when it comes to identifying and managing risk at the frontline.

“Five different variations existed before which was extremely confusing and painful for our workers and contractors who work across multiple sites. It wasn’t an easy process – we each brought our own views, perspectives and things we thought our individual sites wanted and needed. We recognised early on that we wouldn’t be able to please everyone or achieve perfection. We wanted to design the best tool that met the needs of the majority.

“When coupled with the other tools in our FRM system, our Take 5 provides the prompts to change our frontline’s perception and tolerance to risk.”

Moranbah North Mine Underground Coal Mine Worker, Lil Shanley, who has just returned from the International Mines Rescue Competition in Colombia, was also a key member of the FRM development team.

“When someone doesn’t return home, the impact is significant on the families, friends, colleagues, community and the industry. The ripple effect is devastating,” she said. “Ultimately, we’re all here for the same reason – nothing is more important than safety. I’ve worked across almost the whole Bowen Basin and the simple tools are the ones that work best.

“If it’s too complex, people don’t understand it and they won’t complete it properly for fear of getting it wrong. There is nothing confusing about these new tools and the people using them are the ones who have come up with them. I am proud of being able to make the decisions that are going to become a legacy.”

Capcoal Dozer Operator, Emily Page, also involved in the FRM team, said she loved mining and could never go back to a normal nine-to-five job but being on site for a fatality was “the worst thing in the world”.

“If we can make sure everyone goes home every day, that’s the most important thing,” she said. “The most important thing to come out of the mine is the miner. I just don’t want anyone to lose their life, not just in Anglo American but in the industry; it’s got to stop.”

Anglo American defines Fatal Risk as something that has the potential to immediately kill a worker on the frontline during a task. Sadly, these Fatal Risks represent a circumstance where someone in the business or in our industry has tragically lost their life in the past. Under each Fatal Risk are 3-5 Fatal Controls which are the crucial few controls that need to be in place to help prevent a fatality on the frontline. Importantly to meet the criteria of being a ‘Fatal Control’, any worker must have the ability to implement and check that the control is operating as intended– with the power truly being in a frontline worker’s hands.

Shaun Dando, Safety Leadership Practices Coach at Grosvenor, says: “If you asked me until recent times, I would have struggled to identify the Fatal Controls most relevant to me – we have over 1,000 critical controls on file. With FRM, we have narrowed that down and now the controls relate specifically to the Fatal 14, which is so practical and user-friendly.

“I look at that list of 14 and can put faces and names to those risks. I have lost workmates to a number of them, so there is a real reason to have them; it is so we all go home safely – every day,” he said.

Anglo American’s longwall automation milestone recognised in awards ceremony

Anglo American’s innovation-led approach to sustainable mining, FutureSmart Mining™, and a willingness to collaborate with industry parties, has enabled it to achieve a major milestone in longwall operation: 100% machine automation.

This work was recently recognised at the Queensland Mining Awards where team members received the METS Ignited Collaboration Award.

Billed as delivering a significant step change in the safety and efficiency of underground mining, the ability to remove people from hazardous situations at the face and, instead, relocate them to a purpose-built Remote Operations Centre (ROC), has enabled the company to deliver a breakthrough in performance being recognised across the underground coal mining industry.

Anglo American says the development of industry-first systems and technology for this project were completed through working collaboratively with partners including Restech, Aurecon, Komatsu, Eickhoff, Marco and GTick systems.

The miner achieved its first longwall shear fully controlled from surface in late 2018 at its Grosvenor mine in Queensland, Australia, with this milestone achieved on its Komatsu Mining longwall equipment.

Yet, it was the Moranbah North mine that became the first of the company’s three operating longwalls to achieve the 100% automation mark (pictured above).

This mine uses SL 900 shearers from Eickhoff, with a team of operational and engineering experts monitoring the longwall mining process from start to finish. These operators, located in the ROC above-ground, are able to analyse the data and drive safer operations, better decisions and achieve mining excellence, the company says.

Head of Transformation for Anglo American’s Steelmaking Coal business in Australia, Dan Reynolds, said Moranbah North has now become Australia’s most capable remotely-operated underground steelmaking coal mine, with the company’s other mines – Grosvenor and the recently-commissioned Aquila – following close behind.

“All three underground mines are now fully remote-capable, allowing operators to work from state-of-the-art ROCs on the surface of the mine,” he said.

Aquila, Anglo American’s most recently commissioned mine, is also remote-capable, allowing workers to work from a Remote Operations Centre above ground

Step change

The key drivers behind automating longwall operations were to improve safety by reducing personnel exposure to underground hazards; reduce operational variability, to deliver more stable operations and improve efficiency; and improve sustainability of operations, through ensuring automation resilience in various operating conditions.

Much of the technology required to achieve these improvements did not yet exist when Anglo American was considering such a move, and previous industry attempts at achieving sustainable autonomous and remote operations had fallen down, Anglo American said, due to:

  • Enablers not being defined to the level required;
  • Key operational systems being unavailable;
  • OEM operating logic not providing the required operational solutions;
  • The technology enablers not being available; and/or
  • The workforce not being suitably prepared.

Anglo American saw collaboration as a key tool able to overcome these issues, recognising that significant leaps forward in technology were required, including the development of various automation-enabling applications.

“Working with operational teams, the Underground Technology and Automation team developed a leading practice target operating model for integrated remote operations and automation and technology enablers after extensive workforce collaboration,” Reynolds said.

Anglo American says its Steelmaking Coal business has delivered a breakthrough performance in the development and implementation of autonomous longwall technology and remote operations for the underground coal mining industry

“It was identified early in the project that a step change in the supply of systems and technology would be required to achieve project goals. This was reached through working with the OEM and third-party technology providers, which ensured the technology and the software systems provided the solutions that met our mining requirements.”

This work required the team to work collaboratively across its underground operations and corporate partners to develop a series of industry-first safety and production systems that were required to “unlock” autonomous longwall operations, the company said.

The list of innovative, industry-leading processes and systems that the partners have developed, include:

  • A longwall remote operations framework
  • Autonomous shearer:
    • Auto duck – system solution
    • Auto gate road entry – system solution
    • Anglo Seam Steering – system/technology solution
  • Integrated remote powered roof support (PRS) control:
    • Integrated face controller – system/technology solution
    • Remote strata control – system solution
    • Enhanced logic solutions – system solutions
  • A Remote Operating Centre longwall system manager:
    • Integrated central interface solution for longwall remote management comprising:
      • Auto gate road entry
      • Anglo Seam Steering
      • Auto alerts
      • ROC reporting
      • Auto blockage detection
      • Longwall positional control
      • Creep management.

The high levels of collaboration between internal teams and third-party providers enabled these systems to be developed, according to Anglo American.

“The outcomes of this work are significant,” Reynolds said. “It is delivering a significant step change in the safety, stability and sustainability of underground mining.”

The company shed a bit more light on these innovations – many of which have been spoken of by suppliers and mining companies as the missing pieces of the fully-autonomous longwall mining puzzle – in its Queensland Mining Awards application.

“Auto duck”, for instance, allows the shearer to automatically cut under roof supports in challenging strata conditions.

“Auto gate road entry” involves the longwall shearer becoming more “intelligent”, using existing data from scanned files, PRS height data or manual measurements to determine the next cut height for the gate road.

“Seam steering” identifies whether the longwall is in or out of the coal seam by automatically detecting the tonstein band position. This, Anglo American says, is a valuable stratigraphic measure.

“Blockage detection” is conducted using eight cameras across the longwall face, which automatically detect if a face blockage is seen, alerting a ROC operator as necessary.

Similarly, “longwall alerting” sees a ROC operator alerted of potential events or issues. “Tailgate lag control” automatically identifies if the tailgate drive is lagging the face line, while “strata management logic” enables automation of shields.

The company says its Steelmaking Coal business has delivered a breakthrough performance in the development and implementation of autonomous longwall technology and remote operations for the underground coal mining industry.

Anglo American Australia invests in gas, spontaneous combustion management research

Anglo American Australia says it is committing another A$5 million ($3.8 million) towards improving safety at its underground coal mines in the country following the release of recommendations from the Board of Inquiry’s report into an incident that occurred at its Grosvenor mine in May 2020.

Tyler Mitchelson, CEO of Anglo American’s Metallurgical Coal business, said the company is already acting on the recommendations of the report, referencing A$60 million of investment in safety initiatives the company has carried out over the last year.

The latest A$5 million investment will fund underground mining research, in partnership with industry research and technology partners, to improve the industry’s knowledge in certain technical areas, Mitchelson said.

“We have been clear from the outset that the incident on 6 May, 2020, in which five of our colleagues were badly injured was unacceptable,” he said. “The safety of our workforce is always our first priority.”

In the last year, Anglo has put in place a range of measures to address issues that have come to light through detailed investigations and evidence before the Board of Inquiry. Over this period, it has already committed more than A$60 million in technology pilots, additional gas drainage infrastructure, expert reviews and further improvements to a range of processes and controls.

Mitchelson said: “Underground coal mining, particularly in the area where Grosvenor Mine is located, is complex with many interacting considerations and, as the board has identified, further research into certain technical areas such as gas and spontaneous combustion management would benefit the industry. We will be helping to advance knowledge in these areas through our further A$5 million funding commitment.

“The Board of Inquiry’s reports have made a number of recommendations, and we are confident we have already addressed, or will address, these ahead of the restart of longwall mining at Grosvenor Mine later this year.”

Longwall mining operations at Moranbah North Mine safely restarted earlier this month, in line with regulatory approvals, with production expected to ramp up over coming weeks.

Anglo American’s Operating Model, the company’s primary operational management system, is currently being updated at Grosvenor and, together with a range of other measures such as the use of data science, will ensure the company has the very latest in systems thinking, design and technology to ensure operational stability and control, and ultimately safe production, he added.

“The use of automation and remote operation presents us with the single biggest opportunity to remove people from high-risk areas and we are fast-tracking this work across our operations, including commissioning ground-breaking research into automation in development mining with CSIRO,” Mitchelson said.

This work will see the two companies undertake a world-first trial of technology to support automation in the roadway development phase of underground coal mining.

On top of this, Anglo American Australia has commenced a pilot study at Moranbah North to assess the use of pressure sensors to remove power from the longwall face. Initial laboratory testing has been successfully completed and pilot hardware has been installed at Moranbah North Mine, it said. Full-scale hardware and processing systems will be installed at Grosvenor ahead of a restart of operations.

“A further layer of quality control has already been introduced for the supply of Intrinsically Safe underground mining equipment,” the company said.

Anglo American Australia has also invested in data and strata capabilities to change the way it mines, with its newly-established Met Coal Analytics Centre already operationalising gas and strata management analytics to predictive capabilities, with work under way to support its mines.

The company already has gas management improvement measures underway, with A$1.5 billion allocated for gas management over five years across the company’s underground mines. It has also completed a project to increase gas drainage capacity at Grosvenor Mine and introduced enhanced gas management reporting across the business.

Last year, Anglo announced that, to support alignment with Queensland statutory reporting, any gas exceedances of above 2.5% in its underground mines will now be treated as Anglo American HPIs as a High Potential Incident in accordance with the company’s global risk management processes.

Anglo American to test pressure sensor tech following Grosvenor methane ignition incident

A trial of pressure sensors to remove power from the longwall face and the expedition of longwall automation are two of the areas Anglo American is hoping will improve safety at its underground coal mines in Australia, following a methane ignition incident that occurred at its Grosvenor mine, in Queensland, on May 6.

The company began to brief its Queensland-based workforce on the progress of its expert investigation into the methane ignition last week, with Tyler Mitchelson, CEO of Anglo American’s Metallurgical Coal business, saying the company’s focus continues to be on providing ongoing support for the five personnel injured during the incident, four of whom have now been released from hospital, while the fifth remains in a stable condition.

While investigations were progressing and may take some time to formally conclude, Mitchelson said the company would continue to review controls in place across its underground mines as any technical or other findings become available from the investigations.

“We know from our expert analysis that there was a significant and unusual overpressure event on May 6, where a large amount of methane was released into the longwall area, and, seconds later, a brief ignition occurred,” he said. “At this stage, the ignition source has not been conclusively determined and testing continues.

“We also know that in the hours leading up to the incident, there were no non-compliant methane readings in the longwall area.”

Since 2016, the company has invested around A$230 million ($161 million) on gas drainage and gas management activities at the Grosvenor Mine, according to Mitchelson.

“Despite this investment, and extensive controls in place to prevent an underground ignition of methane, we need to further improve our controls to respond to the specific combination of factors of an unusual and large overpressure event in the vicinity of the longwall with a potential ignition source,” he said.

“By drawing on technical learnings and information as it becomes available from the investigations, we have begun a review of our site methane management controls, which includes assessing additional technology options and applying any further improvements across our underground mines.”

As a first step, the company is beginning a pilot study at its Moranbah North mine to assess the use of pressure sensors to remove power from the longwall face as an additional control if a significant overpressure event occurs, he said.

“Whilst pressure sensors are already in use today, across the industry they have not been integrated for this particular purpose,” Mitchelson explained. “Learnings from the pilot will be incorporated across our underground mines and shared with industry.”

Mitchelson said the company has already invested “considerably” in progressing the automation of its longwall equipment, and “expediting this work will also be part of the solution to reducing risks in underground mining”.

Among more recent elements of longwall automation the company has pursued is the ability to operate its longwall shear from an above-ground remote operating centre at the Grosvenor mine.

The company added: “As the largest underground coal miner in Queensland, Anglo American has been at the forefront of technical innovation and has invested significantly in technology to improve safety in its mines, including additional methane detection equipment above and beyond regulatory requirements, digitisation to improve underground communication, and automation of equipment.

“We will continue to prioritise this work.”

Mitchelson said it was unacceptable five personnel were seriously injured on May 6 and that the company would ensure all relevant learnings from investigations underway and the Board of Inquiry are incorporated across its business.

“We continue to support our injured colleagues and their families as they continue their recovery,” he said.

He reiterated that safety comes first, and mining would not resume until it was safe to do so.

While mining activities have been suspended, the Grosvenor workforce has continued to be supported on full pay since the incident to enable the company to work through its future plans, step by step.

Mastermyne gets three more years at Moranbah North, Grosvenor

Mastermyne Group has had its Moranbah Region Umbrella contract with Anglo American’s Metallurgical Coal division renewed for a three-year term, it said.

The contract extends the existing contract at Moranbah North and Grosvenor mines, in Queensland, Australia, and commences from November 15.

Mastermyne said the pact includes an option to extend for an additional two years at Anglo American’s discretion, with work under this contract estimated to contribute revenues of around A$250-$300 million ($170-204 million) over the three-year term.

The scope of work includes design, supply and installation, recovery and maintenance of ventilation structures and devices; installation of secondary support; outbye support and maintenance activities; conveyor belt installations and recovery; and development services.

Moranbah North is an underground longwall coking coal mine that began operating in 1998, while Grosvenor, also a longwall coking coal mine, produced its first longwall coal in May 2016.
Mastermyne said the revenue and earnings from the contract extension have been included in the company’s current 2020 financial year guidance.

Mastermyne CEO, Tony Caruso, said: “The company is very pleased to see the continuation of this long-term relationship, built with Anglo American over the past 17 years. Moranbah North and Grosvenor mines supply high-grade metallurgical coal to the international market for steel production, and we are pleased to support their successful operation.”

Anglo American takes to tablets at Australia UG coal mines

Anglo American says it has launched Australia’s first electronic tablet device certified for use in underground coal mines at its Moranbah North mine, in the Bowen Basin of Queensland.

The introduction of these tables represents a major step forward in the company’s aims to digitise its operations, according to Tyler Mitchelson, CEO of Anglo American’s Australian business.

He added that digitisation was a key part of the company’s FutureSmart Mining™ approach, which applies innovative thinking and technological advances to address mining’s major challenges.

While standard tablets have been used underground at many mines around the world for at least a few years, it is the presence of potential explosive gas mixtures in some underground operational environments – coal, in particular – that inhibits any device being taken below ground that does not meeting ‘intrinsically safe’ regulatory approval. This is due to the potential risk of ignition from energy sources within such devices (eg standard tablets and smart phones).

Mitchelson said: “Following the successful launch at Moranbah North mine, we are now moving towards rapid deployment across all our underground sites including our newly-approved Aquila mine, which will be developed as one of the most technologically advanced underground mines in the world.

“The tablets capture and share real time production, safety and environmental monitoring information with operators, ensuring critical information is readily available to key personnel and removing the need for paper records.”

They also provide direct access to the company’s Safety Health Management System and can be used as a portable video communication device (via Skype) to instantly access personnel working at the surface level, according to Mitchelson. “This will accelerate trouble-shooting and can also be used as a live video link in case of emergencies.”

He added: “Any delays or challenges can be reported and addressed on-the-spot to reduce lost production time, instead of relying on traditional communication methods such as phone calls, underground travel or hard copy reports being submitted and reviewed at the end of a 12-hour shift.”

The tablets are already enabling improved communication and information sharing underground, Mitchelson said. This should ultimately lead to safer, more productive mining, he added.

The introduction of underground tablets followed significant work towards automating longwall operations and digitising the company’s mines, according to Mitchelson, with Anglo American recently completing its first pilot longwall shear from an above-ground remote operating centre at the Grosvenor mine.

The device was developed in collaboration with product manufacturer, Bartec, and tested to achieve certification with the Queensland Government’s Safety in Mines Testing and Research Station, the company said.

Executive Head of Underground Operations in Australia, Glen Britton, said implementation of the tablets followed a successful pilot earlier this year at Moranbah North mine, which was already receiving positive feedback from operators.

“Each week at Moranbah North mine, around 400 statutory reports and 2,500 maintenance work orders are generated. The team there aims to be paperless within two years, and the introduction of these tablets will enable us to remove underground paperwork and transition to electronic storage of statutory and production reports,” Britton said.

“Over the last five years, we have invested considerable resources in the development of this technology, to ensure the product was fit-for-purpose. We sought out a manufacturing partner to help create a new technical solution for managing our data, undertook an extensive certification process and improved underground Wi-Fi capabilities at the mine.”

Mitchell’s UIS drilling contract extended by Anglo American

Mitchell Services has won a contract extension from Anglo American that will see it continue underground coal drilling and gas drainage services at the miner’s Grosvenor and Moranbah North coal mines, in Queensland, Australia.

The variation to the ASX-listed company’s Underground In-Seam (UIS) drilling contract with Anglo American will see Mitchell provide up to six UIS rigs and provide specialist underground services at the sites.

It also resulted in the extension of the contract expiry date to December 31, 2021 with a further two-year extension option available.

Mitchell said: “Whilst the company anticipates a significant long term revenue and EBITDA benefit as a result of this extension and scope increase, the company notes that, given the timing of the variation, the expected start date of the additional rigs and the anticipated level of associated ramp up, the variation is not likely to have a material impact on the recently provided financial year 2019 revenue and EBITDA guidance numbers of A$110-$120 million ($77-84 million) and A$21-$23 million, respectively.”
